Sublingual Microcirculation Data of Patients With Systemic Diseases

National Taiwan University Hospital360 enrolled

Overview

This is an observational clinical study, patients with systemic diseases will be enrolled according to the inclusion and exclusion criteria. 360 patients will received the examination of sublingual microcirculation by using sidestream dark filed video microscope. The microcirculation data includes total small vessel density, perfused small vessel density, microvascular flow index, and heterogeneity index. The patients will be divided into right groups according to their systemic diseases as follows: group 1 hypertension (60 patients), group 2 diabetes mellitus (60), group 3 hypertension and diabetes mellitus (60), group 4 end stage renal disease with hemodialysis (60), group 5 peripheral arterial occlusive disease (30), group 6 coronary artery disease (30), group 7 liver cirrhosis (30), and group 8 anemia (30).
